Updating the 3ware Driver Under SUSE
The following steps describe how to update the 3ware driver under SUSE.

| Note: Backup your original driver before updating in case you need to revert back to it. However, you will not be able to revert back to the original driver if you are booted from that unit.

To update the 3ware driver under SUSE

1 | Download and extract the driver, as described under Downloading the Driver and Firmware.

2 | Backup any critical data prior to updating the 3ware driver.

3 | Change the directory to the location with the extracted driver.

4 | Copy the files to the appropriate directory.

(In the commands below, replace <version> with applicable SUSE version, such as su10)
Replace <kernel string> with applicable kernel (i.e.: 2.6.16.x)
For SUSE Uniprocessor (2.6 kernels)
cp <version>/3w-sas.ko /lib/modules/<kernel string>/kernel/drivers/scsi/3w-sas.ko
For SUSE SMP (2.6 kernels)
cp <version>/3w-sas.smp /lib/modules/<kernel string>/kernel/drivers/scsi/3w-sas.ko
For SUSE high memory systems (2.6 kernels)
cp <version>/3w-sas.big /lib/modules/<kernel string>/kernel/drivers/scsi/3w-sas.ko

5 | Run /sbin/depmod -a

6 | Make sure the file /lib/modules/<kernel string>/modules.dep contains an entry for 3w-sas. If not, add it after the 3w-xxxx entry.

7 | Complete the upgrade by upgrading the initial ramdisk. (Skip to step 10 if you prefer to use insmod 3w-sas.ko, instead.)

Make sure the file /etc/sysconfig/kernel
contains the following line:
INITRD_MODULES=”3w-sas”

| Note: Other modules may be listed before or after 3w-sas depending on the installation. You may see entries likes reiserfs, ext3 or scsi_mod. Leave these entries alone, if present, as the system may need them to boot properly.

8 | Run mkinitrd.

9 | If you are using lilo, use lilo to update to the boot loader.

You should see a printout of kernels that are able to boot on this system after running lilo.

10 | Reboot, if booted from the 3ware controller. Otherwise, continue with step 11.

The driver is now updated.

11 | Stop the current driver module, if loaded:

rmmod 3w-sas

12 | Load the new driver module:

modprobe 3w-sas
If the new driver fails to load properly, confirm that you used correct driver. If your kernel or SUSE version is not supported, you will need to compile your own driver. For more information, search the LSI Knowledge Base for keyword 14546 (use the Advanced Search) at
